tion.

The .present invention relates to the springing of vehicles and especially motor vehicles.

The invention isillustrated in the accom- Y panying drawings,'inwhich- Fig. I shows Va `car-chassis constructed ac cording to the inventionand sectioned vertically.

Fig. II is arrenlarged view of the front portion thereof differently sectioned.

Fig. 1H is a section on A--A Fig. Il.v Fig. VI is an enlarged view ofthe rear part of the chassis 'of Fig. I.

Fig. V shows a modified construction. According to the' present invention the connection between the axles and the chassis is such ythat besides having relative :up and down movement,`said parts can also move relatively fore and aft. The whole relative 'moment is spring controlled; the effect lbeing that when'4 a'wh'eel strikes an obstacle in the road, itfcan move both backwardly and upwardly relatively'to the chassis and thus minimize the shock transmitted. to the latter. f` p j I Referring tothe drawings, 1 indicates the chassisvframe ffolmedV at each end withy dumb-irons 2. 3 is thefront axle,v and Je the Referring more particularly toV Figs-I to 1H, 5 indicates a quarter elliptical leaf spring which is clamped to the chassis frame V at 6. At the free end-of said spring1 5 is a bearing block 7 secured to thespring 5 by a horizontal pivot 8. Pivotally attached to the dumb-iron 2 at 9 is a guide rod 10 which passes through saidbearing block 7, so as to be free for relative sliding and rotating movement therewith. 11 isa slipper which slides freely onvthe guide rod 10, subject to the control'of coil springs 12, which are compressed between said slipper 11 and abutments 13. Said abutments 13 are adjustably clamped on the guide bar 10, to regulate the tension of the springs 12, by set screws 14 or the like.

The axle?) is. formed towards each end with an aperture 15 to pass over the. adja- A'ppiication mea april'so, i920. :sriai'naevzeaa Specivicationof Letters Patent. -P-jgggtggd Apr, 25, 1922.

describedI the "axle` 3 has a definite fore and Aaft movement" under the i control of the springs12, as well as an up and down movement which is permitted by lthelguide bar "10 pivoting about 4the point 9 under the control of the spring 5. l'The spring 5 prelvents longitudinal move-ment of the axle, but otherwise thelatter has universal movement. i

Thefresult is.4 that4 when either wheel 1,7 stril' :esan obstacle on the road, Vit canfmove backwards relatively to the chassis. without imparting a'shock to the latter. ltpasses Owing to of the axlef atone end only doesnot twist the: spring 5, as occurs-with the present spi'nging systems, and the life of said spring 'cent slipper 11, and said slippers 10 are conlnected tothe axle byvertical pivot fjoints 16.

It will be seenthat with thearrangementI 'over the obstacle by deforming the spring 5 1inv theusualgmanner, and the axle thereupon resumes its normal positionfun'der the in-A fluence' of the springs 12 and 5. fthe capacity 3for relative rotation :between 'the'bar 10and/thefbearingblock 7, lifting is therebyprolonged. Moreoverjin the arrangement shewn,th`e chassis frame 1 1s efficiently supported, thatl is, at the points 9 and the intermediatepoints 6, instead of, as usual, at thegend points only.v Thepivotal joint 16 permits canting ofthe axle in a horizontal `plane as whenone wheel on the axle moves horizontally to a different degree p from the other wheel.

The f' rear axle vconstruction shown in Figs..

randjV is substantially thesame as that described inl connection with the -front axle,`

except that owing to the size of the Vrear axle casing l,-and the fact that as ordinarily constructed it does not admit of being-.aper- 4tured, .it is preferred to position the axle under the slippers` 11, for which purpose said slippers are each formed with apertures y 18,'in which the axle is mounted by a vertical l pivot 16.

In the case of therear'axle construction, the drive from the wheels is transmitted through the springs 12, and the forward spring, marked 12a, Vis consequently ymade' as a whole and angularly of the axle with regard to the chassis. For this purpose as shown in Fig. I, the transmission is provided with a sliding joint 19,` and an additional universal joint 20, as Well as the regular universal joint 2l.

The construction permits a 'very much greater spring movement to be attained than feasible with the usual leaf spring and shackle construction. lt also has the ad- Vvantage that either axle can be readily removed from the chassis by disconnecting the joints 9 when the guide rods 10, together with the attached axle and springs l2, can be Withdrawn bodily from the bearing blocks 7.

The construction shown in Fig. V is designed to bring the seating point of the spring 5 substantially over the axle. For this purpose an additional guide rod l()X is provided, rigid and parallel 'With the guide rod i0, and the bearing block 7 is arranged about centrally of said additional guide Y rod 10X.

said bearing block being free to slide and rotate relatively to the guide bar, the axle heilig attached to the other guide bars constituting the guide bar members by means of spring controlled slippers. Y

5. A spring suspension construction for kvehicles comprising a chassis frame, a driving axle, substantially horizontal guide bars on said chassis frame, slippers connected to the axle and movable along said guide bars, said guide bars being pivotally connected to the chassis frame at one end, springs connected at an intermediate point of the'chassis frame and carrying bearing blocks, the guide bars sliding through said bearing blocks and being free for rotation relatively thereto and axledriving means embodying two universal joints and a sliding joint.
